You've long been able to turn your smart lights on and off using Alexa, Amazon's voice-activated virtual assistant, and by now, you've got a lot of options for which bulbs to use. Click through for a look at your growing list of options if you're looking to upgrade.

TP-Link LB100

First up, the TP-Link LB100. At just $20, it's one of your cheapest options, using Wi-Fi to talk directly to your home network, meaning you don't need to pair it with a hub. A version with extra brightness costs $5 more, and a color-tunable version with multiple white light tones sells for $35.

Cree Connected LED

At $15, the Cree Connected LED is even cheaper. It uses Zigbee instead of Wi-Fi, though. That means you'll need an Alexa-compatible hub, such as the Wink hub shown here, in order to let Alexa control it. You can also connect it directly with the Amazon Echo Plus, an Alexa smart speaker with its own built-in Zigbee radio.

Sylvania Smart Plus LEDs

Osram recently spun off its smart lighting brand Ledvance, which now sells Zigbee smart bulbs under the Sylvania brand name (it's confusing, I know). The good news: This Alexa-compatible lineup of Zigbee smart bulbs offers a variety of shapes and sizes, and starts at just $12 each.

Nanoleaf Ivy

Maybe your weirdest-looking Zigbee option: These Nanoleaf Ivy bulbs, which put the light-emitting diodes on the outside of a geometric jigsaw build. Along with Alexa, they also work with Siri and the Google Assistant.

Eufy Lumos LED

Another name to know: Eufy. It's Anker's smart home-centric offshoot brand, and one of the offerings is an Alexa-compatible smart bulb called the Lumos LED that costs just $20. It's a good pick for smartening up a lamp on the cheap, and since it connects with your home network using Wi-Fi, it doesn't require a hub.

GE Sol

Of course, you could also just get a whole new lamp with smarts already built in. That's the idea with the funky-looking Sol from GE -- not only does it work with Alexa, but it has Alexa built into the base, like its own little Amazon Echo.

Lifx Color 1000

The Lifx Color 1000 uses a Wi-Fi radio, so it doesn't need a hub to communicate with Alexa. It costs $60, but it offers full controls. Alexa can change the color of the bulb, too, or even trigger your pre-programmed lighting scenes. ("Alexa, turn on party mode!")

Lifx White 800

If $60 is too much for you, consider the $40 Life White 800, which is just as smart and just as Alexa-friendly. It cuts the colors and costs $20 less, but still offers color-tunability, letting you dial between warm, yellowy tones and hot, bluish-white ones.

Lifx Tile

We're also eagerly awaiting the new Lifx Tile wall panels. Each one features an 8x8 grid of programmable, color-changing lights -- an eyebrow-raising way to add some geeky ambiance into your home. You'll be able to control them using all three major voice assistants -- Alexa, Siri, and the Google Assistant.

Philips Hue White Ambiance LED

If the colors don't matter that much to you, consider downgrading to the Philips Hue White Ambiance LED. At $30, they're less expensive than the full-color Hue bulbs, but just as compatible with Alexa. And, like those Lifx white bulbs, they can change color temperatures.

Philips Hue Bridge

Just keep in mind that with all of these Philips bulbs, you'll need the Hue Bridge plugged into your router. That means you'll probably want to start by buying a starter kit instead of an individual bulb.

Philips Hue White LED Starter Kit

Your best bet? The Philips Hue White starter kit. It's the cheapest entry point to Hue at $70, and it comes with two of those fixed-temperature Hue White bulbs. If you want to add additional bulbs to your setup, that's an option.

Philips Hue BR30 LED

Sengled Element Color Plus LED

Sengled makes smart bulbs that work with Alexa, too. The color-changing Element Color Plus LED uses Zigbee to broadcast its signals -- starting in March, you'll be able to pair it directly with the Zigbee-equipped Amazon Echo Plus.

Haiku Light

Your fanciest option? The Haiku Light, from Big Ass Solutions (best known for its Big Ass Fans). It's a built-in recessed fixture with an integrated motion sensor, full color-tunability, very bright and Alexa compatibility. It's expensive, though: Lights start at $149 and go up to $299, depending on what kind of trim you get.
